A Flow Adjustor is used to represent an equipment resource used to host a Flow Adjusting procedure with a main objective to meet the flow specification of the main outlet stream (which can be either set by the user or by a downstream process) by acting either as a custom flow mixer or as a custom flow splitter. If the flow of the main outlet stream is greater than that of the process stream, then this equipment resource acts as a custom flow mixer used to mix two bulk flow streams, where one of the two streams (the adjustable inlet stream) is of known composition, but adjustable flow, and is allowed to assume any value in order to meet the flow specification of the main outlet stream. If the flow of the main outlet stream is lower than that of the process stream, then this equipment resource acts as a custom flow splitter used to split a stream into two, in a way that the split percentage is not fixed a priori, but it is determined by the program to meet the flow specification of the main outlet stream. The procedure can be executed in a batch or continuous mode.
See Throughput: Equipment Tab.
In Calculate (Design Mode), the user specifies the Maximum Throughput and the system computes the Number of Units and the Rated Throughput. If the operating throughput exceeds the maximum throughput, then the system assumes multiple identical units operating in parallel with an operating throughput of less than the maximum.
In User-Defined (Rating Mode), the user specifies the Number of Units and the Rated Throughput. If the operating throughput exceeds the rated throughput of the step (which is equal to the rated throughput of each unit times the number of units), a warning message is displayed advising the user to increase the number of units or reduce the operating throughput.
The equipment purchase cost supplied by the built-in model is zero, however the user may specify his own costing model if he wishes.
